Hi, I am trying to get F.Port to work on R9MX and Diatone Mamba F722APP Flight Controller (this one https://www.racedayquads.com/products/di...5056606321). I tried UART 5 and proper configuration in Betaflight, but no sticks show up. 

I have R9MM using FPort working on a couple Mamba F405 MK2 flight controllers so I am not new to this but I cannot get this R9MX and Mamba F722APP to work using FPort. In the mean time I have to use SBUS without telemetry, that is the reason for the extra SBUS wire to the receiver. Please see pics and I can provide CLI dump if needed. 

Can anyone help? Any help is greatly appreciated. Thank you.

   
   
   

I wish Diatone would stop confusing people by putting a dedicated S.Port/F.Port pad on their boards without any proper description around how they have configured it (i.e. does it have in inverter in the circuit or not, and how should that port be configured). F7 boards handle inverted signals natively so there is absolutely no need for any manufacturer of an F7 board to put a pad on it which is supposedly dedicated to S.Port/F.Port. An inverted S.Port/F.Port signal can be connected to ANY TX pad on an F7 FC.

And to add to the confusion, FrSky label the port on their receivers which output an uninverted S.Port/F.Port signal as "inverted S.Port/F.Port". They do this because it is inverted from it's normal inverted signal, so it's an "inverted" inverted signal (i.e. an uninverted signal). Thanks FrSky. That is one reason why everyone is now abandoning FrSky products. There are too many frustrations and wasted hours tearing your hair out when trying to set up their receivers.

Anyway, that aside, you need to connect the normal "S.Port/F.Port" output (not the "inverted S.Port/F.Port") from the R9MX receiver to the "S/F.Port" pad on the Mamba F722 APP FC.

Can you please also run both the "dump" and "diff all" commands in the Betaflight Configurator CLI tab and copy/paste the results back here.

The famous SnowLeopardFPV! Thank you so much for helping me, your previous posts have helped me so much in the past.

The inverted part is confusing to me. Here is my CLI dump, thanks again:

By the way, you posted diff all not dump file.

Anyways, wire the Sport on receiver to TX5. Then run the following CLI commands. If that doesn't work, then can you post a dump file.

set serialrx_halfduplex = ON
set serialrx_inverted = ON
Save

Thank you voodoo614, you are a legend! It worked like a dream.

Glad it worked.

So I am new here and I just bought a mamba f722 app mk1 and I have the frsky r9mm and r9m module on taranis qx7 accst. I am wondering if I wire the s/f.port on r9mm to the f.port tab on the flight controller or if I put it on the tx5? Any help would be appreciated

I fried my previous flight controller somehow while trying to upgrade to this receiver and module. So now I am a little leary..

Hey there I got confused by your comment seemed in th few begging we where leaning towards booking the s.f.port on receiver to a tx pad on flight controller. Rather than the dedicated pad?
I have the mamba f722 app mk1 and trying to wire my frsky r9mm receiver via f.port. And want to know if I wire to the dedicated f/s port pad or to a tx pad??
At end of this page looks like other guys was able to get working via tx5 which on ports of flight controller shows f.port.
